GAS-PRESSURE REGULATOR.

To al?, whom it may concern:

Be it known that I, SAMUEL A. BEATTY, a citizen of the United States, residing in the city, county, and State of New York, have invented certain new and useful Improvements in Gas-Pressure Regulators for regulating the pressure of gas in pipes and other devices, of which the following is a specification, reference being had therein to the accompanying drawings.

My invention relates to governing or regulating valves for controlling automatically the pressure of gas in pipes leading from reservoirs for such gas to a burner or to burners; and it consists in certain devices and combinations thereof for producing the desired results, as will be more fully described hereinafter.

Iattain the objects sought to be accomplished by the mechanism illustrated inthe accompanying drawings, in which- Figure l is a sectional elevation of my improved valve, showing the casing thereof, the induction-pipe, the pressure-regulating valve and disk, the chamber underneath said disk, the rod for uniting the valve and disk, the shield for preventing any mercury from coming in contact with the regulating-valve, a chamber for containing mercury, a cup carried on the rod of the. regulating-valve, and an outlet-passage for the gas. Fig. 2 is a perspective view of the conical or tapering plug, upon the lower end of which the seat of the regulating-valve is formed, while its upper portion forms a guide for the valve-rod.

In constructing gas pressure regulating valves having my improved devices and combinations embodied therein I employ a casing, A, which may be of an approved form, that shown in the drawings giving satisfactory results, it being made of cast-iron,or any other material that will not be injuriously affected by the mercury used as a seal, or by the gas. The upper end of this case is provided with a cover, A', which may be hinged to the body A and held in position by screws; or it may be allowed to simply rest thereon, as shown in the drawings. The induction end of the case A is provided with a nozzle, A2, which has a female thread formed in it for the reception of the gas-induction pipe A3. Just above the nozzle A2, or in any convenient por- Serial No. 165,957. (No model.)

l tion of case A, there is formed a chamber, A, within which there is located a valve, B, which is adjusted vertically on the rod B', in order that the position of the valve with reference toits seat and the distance between it and the disk on the upper portion of the rod may be regulated, and thus the opening between the valve and its seat be controlled, so as to allow only a sufficient amount of gas to pass the the valve B is formed upon the lower end of a conical or tapering sleeve or plug, B2, which is fitted snugly in the case A, above the lower extends, as shown in Fig. l, and below which it extends sufficiently far to cause it to enter the chamber At, and thus allow a seat to be formed upon its lower end for the valve B to rest upon when said valve is entirely closed. Upon the upper end of the plug B2 there is formed or placed a bail or cross-bar, B, in which there is an opening, through which the valve-rod B passes, said plug and its bail serving as a guide for the rod. Just above the bail B3 of the plug there is placed an inverted cup, Bt, the diameter of which is sufficient to cause its lower portion to extend below the upper end of the plug, and outward beyond its face of an upwardlyextending flange, B, formed in the case A. The office of theshield B* is to conduct any mercury that may by any means be caused to enter the gas-chamber, soon to be described, from coming in contact with the plug B2 or the valve B. The plug above alluded to has an annular groove formed in its periphery, as shown, into which a setscrew, B6, passes, by which it is held in position even when the case is turned bottom up-I ward. Above the bail B3 there is a disk, C, which is of such diameter as to cause it to nearly or quite fill the space between the walls of the case A at the point where it is placed, and this disk and the walls of the case form a chamber, G3, into which the gas enters through the plug B2. In the lower portion of such chamber there is an annular space, into which the shield BL will direct any mercury that may accidentally find its ',way thereto, from which it may be drawn by inserting a screwplug in the case A, which may be removed valve for supplying the number of burners to v which it is for the time adapted. 'Ihe seat of portion of the enlarged portion of which it outer surface, and also beyond the outer surfor that purpose. Upon the rod B', aud above the disk C, there is secureda sheet-metal cupshaped disk, C', which is adjustable on said rod, its downwardly-projecting portion entering an annular recess, C2, formed in the upper portion of the case A. This annular space is designed for the reception of n1ercury,which acts as aseal and prevents any gas that may pass through or around the disk O from escaping, and thus cause it to press against the under surface of said cup and support the weight thereof, and of the rod B' and valve B. The cup shaped disk C', the rod B', and valve B, acting within the case A, constitute the regulating mechanism, the parts being so constructed and arranged that the pressure of gas upon the under side of the cup-shaped disk G',when greater than is required to keep the valve B in the proper position for allowing just the amount of gas to pass it that is required for the number of burners which the particular governor is adapted to supply, will cause it to be carried upward, thus reducing the iow to the burners; but when the pressure is reduced will fall down, and thus allow a greater amount of gas to pass the valve, the parts of each individual governor being proportioned with direct reference to such result. From the chamber between the stationary disk C and the lower wall ofthe enlarged portion of the case A the gas passes through an outlet-pipe, C", to any desired locality.

I am aware that governing-valves for regulating the pressure of gas at different points have been made and used, in which an annular chamber has been formed for the reception glycerine, and different kinds of of mercury,

liquids, and in which the cup-shaped disk has been placed for operating the valve for controlling the pressure of the gas. I do not therefore claim these devices separately; but,

Having described the devices employed by me, what I claim,and desire to secure by Letters Patent, is-

l. In a gaspressure regulator having a casing containing two annular chambers, as described, the combination of a tubular valveseat, B2, provided with bail B3, and having an outer annular groove for the reception of a screw for holding it in position, the adjustable rod B', valve B, shield B4, disk C, and cup-shaped disk C', all arranged and operating substantially in the man ner and for the purposes specified.

2. In a gas-pressure regulator, the combination of the rod B', carrying at its lower screw-threaded end a valve, B, adjustable upon said screwthread, the valve-seat B2, having perforated bail B3, serving to guide the rod B', the disk C, and the cup-shaped disk C', adjustable upon the upper screw-threaded end ofthe rod B',substantially as and for the purpose specified.

3. ln a gas-pressure regulator, the combination, with the body A, having a portion of its interior tapering,of aconical tubular valveseat, B", provided with a perforated crossbail, B3, and an outer annular groove for the reception of a screw for holding it in position, substantially as shown and described SAMUEL A. BEATTY. Witnesses:
